Stable isotope analysis of feces can provide a non-invasive method for tracking the dietary
habits of nearly any mammalian species. While fecal samples are often collected for
macroscopic and genetic study, stable isotope analysis can also be applied to expand the
knowledge of species-specific dietary ecology. It is somewhat unclear how digestion
changes the isotope ratios of animals' diets, so more controlled diet studies are needed. To
date, most diet-to-feces controlled stable isotope experiments have been performed on …
